Who is the unbelieving wife?

       The unbelieving wife (I Cor. 7:14), says Paul to the Corinthians, is sanctified by her husband. Though he is a Christian and she is not, his belief sanctifies the union. Paul goes on to say that the faith of one Christian parent gives to the children a near relationship to the Church, just as if both parents were Christians. The children are regarded not as aliens to the Christian faith but as sharers in it. Paul presumed that the believing parent will rear the child in the Christian principles.
       He makes the same point in regard to husbands, saying that "The unbelieving husband is sanctified by the wife."  I Corinthians 7:14
